I’m trying to add an RSS widget to my sidebar so people can follow my blog via an RSS feed in addition to email. When I try to add the RSS widget, it wants me to enter an URL. What do I enter? I tried adding /?feed=rss to my blog address but when I do this it shows in sidebar with the words “unknown feed” and gives an error msg. Am I suppose to enter the url of a feeder instead? I am really new at all this, as I imagine you can tell.
